Alex Boone won the starting role in camp and had a stellar performance last week (+4.3). Corey Williams and the rest of the Lions formidable DL should prove to be a stiffer test. Williams faded a bit in the second half of the season last year, but had his best performance in the game against the 49ers (+4.0). He was quick shedding blocks and causing general mayhem on his way to four hurries and three run stops. Last week against the Rams, he was once again the star (+3.4) for the Lions' defense with a sack, forced fumble, QB hit, and two run stops, while also drawing two holding penalties — all in a mere 35 snaps. For a sample of his work, just watch him make a mess of an attempted double team at the 8:24 mark of the third quarter. There are other Lions defenders with more notoriety, but no doubt Boone and the rest the OL will give Williams plenty of attention.
